Q(β-)=-6.62×103 keV SYS(n)= 8.64×103 keV 8S(p)= 3.83×103 keV SYQ(α)= 7365 keV 11
Reference: 2012WA38

General Comments:

Activity produced by 198Pt(40Ar,4n) E=184-208 MeV. 95.7% isotopically enriched target. 234Cm was identified by α - α correlations with daughter nuclides of the α-decay chain. Measured Eα=7239 keV 10 (2002CaZZ).

Q-value: Note: Current evaluation has used the following Q record





E(level)
(keV)
Jπ(level) T1/2(level)
  0.0 0+ 51 s 12 
% α ≈ 40
% ε ≈ 20
% SF ≈ 40
